Need help with chemistry homework A student adds 5,0 mol ethanol, 6,0 mol ethanoic acid, 6,0mol ethyl acetate and 4,0 mol water into an erlenmeyer flask. He waited until it balanced and noticed that there was 4,0 mol of ethanoic acid left. Calculate the equilibrium constant. I got this and made an ICE tablet with it: CH3COOH (aq) + C2H5OH (aq) <-> C4H8O2 (aq) + H2O (l) 6 5 0 0 -2 -2 +2 +2 4 3 2 2 And then I used this: K=[C4H8O2][H2O]/[CH3COOH][C2H5OH] and I got = 0,3333 Is this correct? Because this felt a bit way too easy. And I don't know what am I supposed to do with 6,0mol ethyl acetate and 4,0 mol water. Or do I even need them?
